Side Bearings Caps
When putting on side bearing caps, be sure to
discriminate the right-hand cap from the left-
hand one by referring to match marks scribed
at the time of disassembly.
Then, after carrying out “Bevel gear backlash
adjustment” as described on p. 16-10 torque cap
bolts to specification.
16-6. INSTALLATION
Reverse removal procedure for installation,
noting the following.
Differential
Before installing differential ass’y to axle hous-
ing, clean mating surfaces of differential carrier
and housing and apply sealant to them.

Front Axle Shaft and Steering Knuckle
For installation them, refer to “Front Suspen-
sion Installation” in SECTION 17 of this manual.
Rear Brake Drum
For installation of rear brake drum, refer to
“Rear Brake Installation” in SECTION 19 of
this manual.
Differential Gear Oil
Refill differential housing with new specified
oil. Refer to “MAINTENANCE SERVICE” in
this section for refill.
Brake Circuit Air Purging
If brake pipe (right & left) was disconnected
from wheel cylinder as in Fig. 16-9-2, make sure
to purge air out of brake circuit. Refer to
section 19. BRAKES for “air purging" operation.
Then check to ensure that joint seam of pipe is
free from oil leak.

(2) Be sure to insert lock washer after adjust-
ment and tighten lock nut @ to specified
torque. Then bend a part of lock washer
toward bearing nut (body side) and another
part toward lock nut (outside) so that these
2 nuts are locked.

Recheck that bearing starting preload is
within specification.
Upon completion of adjustment, be sure to
install axle shaft drive flange or free wheeling
hub (if equipped), circlip, disc brake caliper
& holder and wheel.
Refer to “INSTALLATION” in this section.
King Pin
[ Inspection and adjustment ]
Where tapered roller bearings holding 2 kingpins
at each front wheel are in good and properly
preloaded (tightened) condition, there will be
no appreciable rattle of wheel. To check king-
pins and their tapered roller bearings, jack up
the front end and shake wheel to feel any
rattle, as shown in figure. If rattle is felt, elimi-
nate it by properly decreasing the shim thick-
ness. The shim is located between flanged part
of kingpin and knuckle.
The above-mentioned method of making a shim
adjustment demands a high degree of skill on the
part of the serviceman. The alternative method
is to adjust shim thickness by referring to the
torque resistance which knuckle arm offers
when pulled in the condition shown in figure.
For this method, the reference torque value is
established as indicated below, and you are to
increase or decrease shim thickness to produce
this torque value,
NOTE:
After removing wheel and steering knuckle oil
seal and disconnecting tie rod end, this check-
ing and adjustment shouId be carried out.

Steering Lock
1) After removing steering column, loosen and
remove steering lock mounting bolts. Use care
not to damage aluminum part of steering
lock body with center punch.

2) Remove steering lock assembly from steering
column.
Gear Box
1) Remove joint bolt.

2) Remove radiator under cover, and disconnect
ball stud of drag rod using special tool and
steering damper from pitman arm.

in below figures. If not, add prescribed gear oil,
SAE 90.

[Adjustment of worm shaft starting torque]
The steering gear box is provided with adjust-
ing bolt @ which gives preload to sector shaft.
Fig. 18-19 (1)Adjusting bolt
Make an adjustment according to the following
procedure.
1) Check worm shaft to ensure that it is free
from thrust play.
2) Position pitman arm in parallel with worm
shaft as shown below.
(With pitman arm in this position, front
wheel is in straightforward state.)

Steering Handwheel
Two requirements must be met, among others,
in installing and setting steering wheel: 1) check
to be sure that handwheel play meets specifica-
tion, and 2) set it in such a way that, with front
wheels in straightforward state, its two outer
spokes are horizontal.

Tie Rod and Tie Rod End
1) Install tie rod end to tie rod, aligning each
lock nut to respective marks scribed before
disassembly.

2) Connect tie rod end to knuckle and tie rod
to drag rod. Tighten castle nut until holes for
split pin are aligned, but only within specified
torque.
3) Bend split pin.
4) Inspect for proper toe (Refer to 18-8 WHEEL
ALIGNMENT).
5) After confirming proper toe, tighten tie rod
end lock nuts to specified torque.
18-8. WHEEL ALIGNMENT
Front alignment refers to the angular relation-
ship between the front wheels, the front
suspension attaching parts and the ground.
Generally, the only adjustment required for
front alignment is toe setting. Camber and
caster can’t be adjusted. Therefore, should
camber or caster be out of specification due to
the damage caused by hazardous road conditions
or collision, whether the damage is in chassis
frame (body) or in suspension should be deter-
mined and damaged body should be repaired or
damaged suspension should be replaced.
Toe Setting
Toe is the turning in or out of the front wheels.
The purpose of a toe specification is to ensure
parallel rolling of the front wheels (Excessive
toe-in or toe-out may increase tire wear).
Amount of toe can be obtained by subtracting
“A” from “B” as shown in figure and therefore
is given in mm (in.).
WHEEL TOE-IN“6” - “A” = Toe-in
